CVE-2026-24838Network attack vector

Stored XSS via rich-text module titles

Published Jan 27, 2026 · Updated Jan 28, 2026

Stored XSS in DNN Platform before 9.13.10 or from 10.0.0 before 10.2.0 allows remote authenticated users to execute scripts. The module-title path accepts rich-text content and renders embedded script markup without neutralizing executable input. High-privileged access is required to store a crafted title; later page rendering executes the script in a visitor's browser.
